Electricity is an essential comfort to support our daily activities. With the competitive increase and energy costs by the industry, new values and opportunities for delivering electricity to customers are produced. One of these new opportunities is electric vehicles. With the arrival of electric vehicles, various challenges and opportunities are being presented in the electric power system worldwide. For example, under the traditional electric power billing scheme, electric power has to be consumed where it is needed so that end-users could not charge their electric vehicles at different points (e.g. a relative's house) if this the correct user is not billed (this due to the high consumption of electrical energy that makes it expensive). To achieve electric mobility, they must solve new challenges, such as the smart metering of energy consumption and the cybersecurity of these measurements. The present work shows a study of the different smart metering technologies that use blockchain and other security mechanisms to achieve e-mobility., Comment: 2020 IEEE 4th Electric Vehicle International Symposium

The Digital Transformation through the Technologies of the Fourth Industrial Revolution has had a good impact on practically all human activities, and the electricity grid is no exception. The Grid is responsible for providing electrical energy to all human processes, and living without it is practically impossible. The inclusion of information and operation technologies (IT and OT) to the electricity grid have given it some "intelligence" to provide new services to end-users and utilities, such as consumption measurement and billing in near real-time, cuts and reconnections automatically, monitoring of power quality, demand response programs, fault detection, among others. Despite these new advantages, the use of IT and OT has several advantages, among the most important: costs, the large volume of data generated, and above all, the security of information in all the processes of the Smart Grid. This work presents a review of the current state of the art regarding the topic of cybersecurity in Smart Grid as follows: the Introduction section shows the basic concepts of cybersecurity in smart power grids. In the chapter on methods, the related works that aim to solve the problem posed are shown. In the results section, a comparative table is made between the main works. Later the results are discussed, and conclusions are reached.

With the proliferation of smart meters in smart electric networks, new applications and challenges to the energy sector are brought, mainly with respect to cybersecurity and data privacy. To protect them, a mechanism that helps protect data is necessary, with cryptography being one of the most used. This paper presents a comparison of algorithms that can be used in smart meters to safeguard the confidentiality, integrity, and availability of the data generated by smart meters and that, in turn, are efficient to process in this class of embedded devices.
